Abstract

Background: Early diagnosis by electrocardiogram helps doctor who is predicting the location of culprit coronary artery in acute ST-segment elevation myocardial infarction so that it can be treated rapidly.Objectives: To determine the sensitivity, specificity, positive predictive value, negative predictive value of electrocardiogram criteria for locating culprit coronary artery lesions compared with the results of percutaneous coronary angiography. Materials and methods: A cross- sectional descriptive of 52 patients admitted to the interventional Cardiology Department at Can Tho Central General Hospital from January 2020 to October 2020. Results: The rate of men was higher than women, hypertension was the most common underlying disease. The proximal and distal LAD lesions had a sensitivity: 85.7% and 71.4%, a specificity was 66.7% and 71.4%. For the proximal and distal RCA lesions, the sensitivity was 75% and the specificity was 83.3%,75%, for the left circumflex artery had a sensitivity and specificity was 80% and 66.7%. Conclusions: The electrocardiogram is useful in predicting the culprit coronary artery lesions in acute ST-segment elevation myocardial infarction with high sensitivity and specificity.
